o-Phthalaldehyde Chemical Properties,Uses,Production

Chemical Properties

Light yellow powder

Uses

o-Phthalaldehyde can be widely used for precolumn derivatization of amino acids in HPLC separation or Capillary electrophoresis. For flow cytometric measurements of protein thiol groups.

Uses

o-Phthalaldehyde can be used for precolumn derivatization of amino acids for HPLC separation and for flow cytometric measurements of protein thiol groups.

Uses

Precolumn derivatization reagent for primary amines and amino acids. The fluorescent derivative can be detected by reverse-phase HPLC. The reaction requires OPA, primary amine and a sulfhydryl. In the presence of excess sulfhydryl, amines can be quantitated. In the presence of excess amine, sulfhydryls can be quantitated.

Uses

Disinfectant. Reagent in fluorometric determination of primary amines and thiols.

Definition

ChEBI: A dialdehyde in which two formyl groups are attached to adjacent carbon centres on a benzene ring.
